Co-operating with the most important manufacturers of ultra-sound and eddy-current instruments, A.Z. Impianti builds systems to detect, mark and sort bars, pipes and hexagons, and mechanical raw or finished pieces, which may show defects from internal cracks or defects due to external rolling, peeling or drawing lines. The company supplies automatic testing lines formed by: independent charging zones; material entry rollers; central testing zone built by pinch roll or triples and tables for the testing instruments; exit rollers and sorting of good pieces from defective ones collecting them into the relevant good/no good cradles. The company supplies automatic testing lines (single pinch roll or triples, test instrument tables, separate testing stations) to be inserted into existing testing lines. They also project complete lines for off-line testing on bars, pipes, hexagons and mechanic components.
